Bits Up!: DNS Prefetching for Firefox

2009 Jun 22, 3:28Details on Firefox's DNS prefetching: "The Firefox implementation takes this approach one step further than just pre-resolving anchor href hostnames. It uses the prefetch logic on URLs that are being included in the current document. By this I mean that it uses the prefetch logic on things like images, css, and jscript that are being loaded right away, in addition to anchor links which might be clicked on at a slightly later time."PermalinkCommentsdns dns-prefetching html performance networking firefox mozilla technical

Paleo-Future: Robots vs. Musicians (1931)

The consequences of using recorded music at theatre performances rather than live musicians are, "Monotony in the theatre - corruption of taste - destruction of art."

Awesome Spokesmen Billy Mays and Vince Offer

2009 Apr 8, 4:06
Vince Offer photo from onebutan-iphoneBilly Mays photo from onebutan-iphone

There can be no doubt that infomercial pitchmen Billy Mays and Vince Offer are awesome, but how can I decide which is my favorite?

Infomercial Performance.
Among other things they sell Zorbeez and ShamWow respectively, both of which are absorbant towels so first up I can get a somewhat apples-to-apples comparison on informercials for comparable products. Thankfully someone has created a Vince Offer vs Billy Mays youtube video featuring these informercials.

Billy has an upbeat yell to everything he says while Vince has an endearing condescension to his "You followin' me camera guy?" In the end I must give this one to Vince Offer.

Extracurriculars.
Billy Mays has a new show Pitchmen on the Discovery Channel, a reality show involving folks pitching inventions to the pitchmen Billy Mays and someone else. Vince Offer was arrested for assaulting a prostitute. A clear win for Billy.
Intra-pitchman Interactions.
Billy has challenged Vince to a pitchman-off which on the surface sounds like a point for Billy, but if you listen to the challenge Billy says that Vince attempted to extend the olive branch. Billy Mays calls out Vince on the Adam Corolla Show

Deriving a Non-Recursive Fibonacci Function Using Linear Algebra

2008 Aug 20, 10:51

In my Intro to Algorithms course in college the Fibonacci sequence was used as the example algorithm to which various types of algorithm creation methods were applied. As the course went on we made better and better performing algorithms to find the nth Fibonacci number. In another course we were told about a matrix that when multiplied successively produced Fibonacci numbers. In my linear algebra courses I realized I could diagonalize the matrix to find a non-recursive Fibonacci function. To my surprise this worked and I found a function.
The Nth Fibonacci value is (1 + sqrt(5))^N - (1 - sqrt(5))^N all over sqrt(5) * 2^N
Looking online I found that of course this same function was already well known. Mostly I was irritated that after all the algorithms we created for faster and faster Fibonacci functions we were never told about a constant time function like this.

I recently found my paper depicting this and thought it would be a good thing to use to try out MathML, a markup language for displaying math. I went to the MathML implementations page and installed a plugin for IE to display MathML and then began writing up my paper in MathML. I wrote the MathML by hand and must say that's not how its intended to be created. The language is very verbose and it took me a long time to get the page of equations transcribed.

MathML has presentation elements and content elements that can be used separately or together. I stuck to content elements and while it looked great in IE with my extension when I tried it in FireFox which has builtin MathML support it didn't render. As it turns out FireFox doesn't support MathML content elements. I had already finished creating this page by hand and wasn't about to switch to content elements. Also, in order to get IE to render a MathML document, the document needs directives at the top for specific IE extensions which is a pain. Thankfully, the W3C has a MathML cross platform stylesheet. You just include this XSL at the top of your XHTML page and it turns content elements into appropriate presentation elements, and inserts all the known IE extension goo required for you. So now my page can look lovely and all the ickiness to get it to render is contained in the W3C's XSL.

YouTube - Norm MacDonald - Bob Saget roast

2008 Aug 18, 4:06Norm MacDonald performs at the roast of Bob Saget. Must be viewed with context of entire roast in mind in which roasters spout profane offensive insult humor. Norm does a sort of un-roast consisting of jokes from the back of milk cartons or cracker jack boxes. Not at all offensive. Funny conceptually and of course since its Norm MacDonald its hilarious in practice. Later described by Jim Norton: "Watching your set, was like watching Henry Fonda pick blueberries."PermalinkCommentsnorm-macdonald bob-saget roast comedy-central humor video youtube

Dr. Horrible Link Roundup

2008 Aug 10, 3:33

Doctor Horrible's Sing Along Blog is an Internet only show you may have already watched and heard everything about. If you missed this somehow, its a musical by Joss Whedon (Buffy the Vampire Slayer, Firefly) staring Neil Patrick Harris as an aspiring super villian who can't get up the courage to talk to his laundromat crush. Its very funny, fairly geeky, and on the Internet so of course I've enjoyed it thoroughly and have some links to share. It surprised me how many blogs that I don't usually see posting the same things telling me about it: first on Eric's blog, then The Old New Thing, and even Penny-Arcade.

Dr. Horrible's again available online via Hulu with commercial interruption.

Check out the official fan site. They link to such things as the owner of Dr. Horrible's house. He had appeared on Monster House, a reality show about remaking people's homes like Monster Car or Pimp My Ride is about remaking folk's cars, and had his house turned into a evil scientist's lab. Consequently its a perfect fit for Dr. Horrible and in return the owner appears in one of the final scenes and in the credits as the 'Purple Pimp'. Apparently the purple suit is his. Also on his blog you can find out what's happened on that big chair that appears in the show. All I'll say about that is, good thing Neil Patrick Harris wears a lab coat while sitting on it.

At the recent Comic Con some attendees took video of the Dr. Horrible Comic Con panel (video clips contain spoilers) some of which I've grouped together. Besides the videos containing the creators and stars of the musical who are all hilarious (see Felicia Day's comment on twittering) there's also some excellent bits about a possible second installment and information on the impending DVD. To finish off this series of Dr. Horrible links check out this Venn Diagram of Felicia Day's work.

The Wii Fit's Mind Games

2008 Jun 19, 2:49

Wii Fit LogoSarah received her Wii Fit a few weeks ago. The Wii Fit is a game for the Wii and a balance board accessory that can tell how you're standing on it: leaning forward, standing on one foot, leaning backward and mostly on your left foot, etc. The game puts you through various exercises grouped into the categories of aerobic, balance, strength, and yoga. It also lets you set goals and keeps track of how well you do, how long you play, and a graph of your weight.

The portion I didn't expect were the mind games. Sarah turned it on after not using it for a day and it said something to the effect of 'Oh, didn't have time to exercise yesterday? Huh. Interesting....' I'm paraphrasing of course but the Wii Fit was definitely trying to lay down some guilt. In another instance when starting up the Wii Fit Sarah was asked 'Did you know that Dave has been using Wii Fit?' She selected yes and it then asked her how she thought I was progressing giving her four options. She selected the worst one, that I was getting worse (jokingly I hope) and it told her to tell me that, but not to use those words. In conversation Sarah should mention to me that I've been "living large". Now I'm not paraphrasing. It reminded me a bit of this xkcd comic 'Zealous Autoconfig'. Hopefully this is the extent of the manipulation and mind games that the Wii Fit will perform.

NetFlix Media Center and Ong-Bak

2008 Jun 15, 7:57

Ong-Bak movie poster.I just installed vmcNetFlix which lets you watch your on demand NetFlix movies via your Vista Media Center or any Media Center Extenders like the Xbox 360. It works well but fails poorly with some cryptic error messages and long timeouts. Be sure to get NetFlix on demand movies working in your browser before installing this plugin. Once I did that everything worked very well.

To test it out I watched Ong-Bak: The Thai Warrior in which Ting must travel from his country village to Bangkok where he works with his cousin in the city to recover his village's stolen religious artifact. Its a mix of Perfect Strangers, Street Fighter and Pad-See Ew. Martial arts movies, like porn and video games, aren't required to have a strong plot but Ong-Bak has a fine plot line and enjoyable Thai martial arts. I saw the Tiger Knee in there several times. An enjoyable movie that reminded me of watching martial arts movies with my friends in high school.

Feed Folder Deprecated; Use Internet Explorer 8

2008 Mar 7, 7:20

Internet Explorer 8 has made my plugin Feed Folder obselete in functionality and implementation -- which is good!

IE8's Feed Folder feature screen shot.IE7 Feed Folder plugin screen shot.

I made Feed Folder for IE7 because I wanted the Live Bookmarking feature from FireFox. The Feed Folder plugin for IE7 would allow you to display your feeds as virtual folders in your Links Bar. When your feed is updated the virtual folder is updated as well with the new feed items. I use del.icio.us to store all my links so I could add virtual folders of my daily links, my friends blogs links, quick reference links, etc. etc.

My plugin relied on shell folders to implement the virtual folders I described above, but IE8 doesn't support shell folders in the Favorites Bar. But I'm OK with Feed Folder not working in IE8 since there's a much better implementation already there. IE8 does better than my plugin on a number of points: First, there isn't the horrible perf. issue that my plugin had on Vista. Second, when a feed is updated the virtual folder flashes to note the change in status. Third, unread items are bolded and the bolding bubbles up from feeds contained in subfolders. And lastly, the middle click button is supported to open items in a new tab.

Accordingly, I don't plan to work on Feed Folder anymore unless someone comes up with a good reason. Instead I mark Feed Folder deprecated and suggest you use Internet Explorer 8 instead.

To use this feature in IE8 simply drag a feed from your feed list in your Favorites Center onto your Favorites Bar. Or, when viewing a feed, click on the 'Add to Favorites' Star Plus icon thing in the upper left, and select 'Monitor on Favorites Bar'. A .url Internet Shortcut file is produced as usual, but if you open up the .url file you'll see there's some additional info about the feed.
